no sound on ubuntu 16.04 .In setting it say dummy sound after downloading on to a mini pc it says dummy sound what does that mean .what can i try ?
pulseaudio -k && sudo alsa force-reload
I just had this problem a couple hours ago. Usually just switching to a different device fixes it but not this time. So I used:
rm ~/.pulse/ # In my case this directory was empty rm ~/.config/pulse/* pulseaudio -k
